#rtx4090

It is interesting it took this long to find out the root cause for these issues. It never was about the connector itself. The connector allowing poor connection to be made was naturally contributing as it then resulted in the wires overheating and connectors melting. But that wasn't the root cause.

The overheating / melting occurs because of the removed safety feature on the card side.

#NVIDIA consciously simplified the RTX 4090 power input circuitry to remove a safety feature that existed in the RTX 3090. In the 3090, two wires would get combined to one, and there were three separate power shunts. Any problem in the power delivery would lead to the card shutting down.

In the 4090, all six 12V lines combine to a single terminal, which is then power-shunted as one. Any problem in the individual wires or connector pins will not be noticed. If there is a power delivery problem, the remaining connections will take the load and melt or catch fire. RTX 4090 cards have been melting connectors regularly.

So, RTX 5090 is now available. The cards are several thousand dollars/euros. They also omit this RTX 3090 security feature that likely cost a maximum of a couple of euros/dollars to add.

When taking geo mean across 60+ benchmarks of #CUDA / #OptiX / #OpenCL / #Vulkan Compute, the GeForce RTX 5090 was delivering 1.42x the performance of GeForce #RTX4090. On performance-per-Watt GeForce RTX 5090 tended to deliver similar power efficiency to the RTX 4080/4090 graphics cards.
GeForce RTX 5090 Founders Edition was running cooler than many of the other Founders Edition graphics cards tested.

Likely in response to the very popular #IntelARC #B580 video cards being priced at $250, #Nvidia has announced the first four #RTX5000 cards, including the #RTX5070 priced at $550. Nvidia even claims that it’s as powerful as the previous #RTX4090. Highly unlikely. #CES2025 #tech theverge.com/2025/1/6/24337396
